TreeElementStyle

TreeElementStyle

is an option for Tree and related functions that specifies what styles should be used for subtree elements.

Details

  • TreeElementStyle allows specifying the style of the root node of a tree, as well as that of any subtrees at positions matching a pattern.
  • The following option settings can be used:
  • Automaticuse the automatic style
    styleuse style for the node »
    Allstyleuse style for all nodes »
    TreeCases[pattern]styleuse style for nodes with data matching pattern »
    "Leaves"styleuse style for leaves »
    "NonLeaves"styleuse style for non-leaves »
    {pos1style1,pos2style2,…}use stylei for the node at relative position posi »
    {patt1style1,patt2style2,…}use stylei for nodes at positions matching patti »
  • Subtrees with no explicit element style posstyle are taken to use the automatic style.
  • TreeElementStyle can apply to points, lines and faces.
  • To specify multiple style directives, use Directive[style1,style2,…].
  • Subtree element style specifications are effectively applied in the order TreeElementStyle, TreeElementStyleFunction and TreeElementShapeFunction, with later specifications overriding earlier ones.

Style an individual node:

Specify a list of node styles:

Use the same style for all nodes:

Specify styles for the leaves and for the non-leaves:

Specify positions using position patterns:

Specify positions using data patterns:

Properties & Relations  (4)

Styles for nodes can be specified by position:

Styles specified by a subtree take precedence over styles specified by its ancestors:

A position {i,j,…} in a subtree refers to its subtree at relative position {i,j,…}:

A relative position {2} at position {1} refers to the global position {1,2}:

In general, a pattern patt applies to subtrees at global positions {i,j,…} that match patt:

A list of patterns {patt1,patt2,…} applies to relative positions {i,j,…} that match the patti:
